It's only for the lowest order byte, and I had the polarity wrong.

Derek Hower 7f012ef8da ruby: made mapAddressToRange based off a bit count 2009-08-04 23:05:37 -05:00
Derek Hower 33b28fde7a slicc: added MOESI_CMP_directory, DMA SequencerMsg, parameterized controllers 
This changeset contains a lot of different changes that are too
mingled to separate.  They are:

1.  Added MOESI_CMP_directory

I made the changes necessary to bring back MOESI_CMP_directory,
including adding a DMA controller.  I got rid of MOESI_CMP_directory_m
and made MOESI_CMP_directory use a memory controller. Added a new
configuration for two level protocols in general, and
MOESI_CMP_directory in particular.

2.  DMA Sequencer uses a generic SequencerMsg

I will eventually make the cache Sequencer use this type as well.  It
doesn't contain an offset field, just a physical address and a length.
MI_example has been updated to deal with this.

3. Parameterized Controllers

SLICC controllers can now take custom parameters to use for mapping,
latencies, etc.  Currently, only int parameters are supported.

Steve Reinhardt a13a706a20 Fix setting of INST_FETCH flag for O3 CPU. 
It's still broken in inorder.
Also enhance DPRINTFs in cache and physical memory so we
can see more easily whether it's getting set or not.

Steve Reinhardt 1c28004654 Clean up some inconsistencies with Request flags. 2009-08-01 22:50:13 -07:00
Steve Reinhardt c0755e6085 Rename internal Request fields to start with '_'. 
The inconsistency was causing a subtle bug with some of the
constructors where the params had the same name as the fields.
This is also a first step to switching the accessors over to
our new "standard", e.g., getVaddr() -> vaddr().

Gabe Black 1e04b6281d ARM: Make the ARM native tracer stop M5 if control diverges. 
If the control flow of M5's executable and statetrace's target process get out
of sync even a little, there will be a LOT of output, very little of which
will be useful. There's also almost no hope for recovery. In those cases, we
might as well give up and not generate a huge, mostly worthless trace file.

Gabe Black a41e132007 ARM: Make native trace only print when registers are changing value. 
When registers have incorrect values but aren't actively changing, it's likely
they're not being modified at all. The fact that they're still wrong isn't
very important.

TLBUnit no longer used and we also get rid of memAccSize and memAccFlags functions added to ISA and StaticInst

and the result is checked before it's sent out to memory.

Korey Sewell 6211fe5d2e inorder-float: Fix storage of FP results 
inorder was incorrectly storing FP values and confusing the integer/fp storage view of floating point operations. A big issue was knowing trying to infer when were doing single or double precision access
because this lets you know the size of value to store (32-64 bits). This isnt exactly straightforward since alpha uses all 64-bit regs while mips/sparc uses a dual-reg view. by getting this value from
the actual floating point register file, the model can figure out what it needs to store

Separate the TLB from the CPU and allow it to live in the TLBUnit resource. Give CPU accessor functions for access and also bind at construction time
